Hi All,
When I use the function Replace(unwanted, replacement) of stringBuilder, if the "replacement" string length is bigger than "unwanted" length then the method throws "OutOfRangeException". I have microframework 4.2.
Thanks in advance.

I haven't had issues with the replacement text being longer than what it is replacing.

I found a pretty interesting bug back when 4.2 was still alpha-ish; outlined here

Have you tried with a shorter base string? You could possibly be running out of memory on the netduino. Try and compile a simple .NETMF project and run it locally on your PC. If it works there, but not on your netduino, I'm guessing you're asking a bit too much from it.

Possible workaround: Look at an example on the thread I linked above (first post in that thread, iirc) that reads through one char at a time and does the replacing that way. It was Valkyrie-MT's example. [WARNING: It's not pretty]

Hi folks,
I can't find String.Replace in my NetDuino Plus project. This is the error:
"String does not contain a defenition for 'Replace' and no extension method...bla bla bla"

I use .Net MF 4.1

You cant actually do a <string>.Replace(), as strings don't have that method in the micro framework.

You can, however, do what bulletprooffool did and roll your own Replace() function, and call it wherever you need it. I like to have a utils.cs class to keep this kind of crap handy.

[OR]

If you don't want to get that fancy/reusable with it, you can just do it inline-ish by doing exactly what is in that function; make the String a StringBuilder, do your fiddling, and then assign it back to your original gangster String. That will look a little something like this:

String tacoString = "I like Tacos";
// "I like Tacos"
StringBuilder  tacoStringBuilder = new StringBuilder(tacoString);
tacoString = tacoStringBuilder.Replace("like","love").ToString();
// "I love Tacos"

Just be sure you get that last .ToString() in there; I don't think it will compile if you don't.

Hope this helps.

From what I'm reading about the .netmf, there are hints of a simple SNMP lib being available in 4.3 (release at the time of this post is 4.2). (comments on a link (http://netmf.codeple...m/workitem/1232) previously posted in this thread. (also- i know this is an older thread-- I just thought I would update it as its the #1 result in google for "netduino snmp") Mark

I just randomly came across this library that says it supports .NET MF 3.5

Sharp SNMP (#SNMP) Library

The library looks a bit large, so I'm not sure if it will fit on the netduino. However, it is open source.. so you could possibly strip it down a little.

I did not check it out yet, though. I might dive into it this weekend. I really want to poll my Airport Extreme for current throughput and use an analog gauge of some sort to display it.

Sounds simple enough.. (how most of my hair-brained ideas start)

I cant read. It's for the Compact Framework.. not Micro

I see you're using O7 and O8. The code just isn't prepared for that.

Totally missed the octave range limit in the documentation. Thanks for the info (and changeset)
